VetteNuts Insulation Kit

VetteNuts has sold 1000's of these kits and we build these in house
and it has been sold on the for years.
There is a lot of customer feedback about these kits on the forum.

The C5 Pre-cut Insulation kit comes with everything you need to insulate and provide sound deadening in your Corvette. We have been selling this kit for 10 years and have made revisions over time to make the kit fit your C5 the way it should. 



Our kit is a non-fiberglass, non-asphalt based product which weighs in at 3.5 lbs, for those who are weight conscious, it rejects 97% of the radiant heat, and has a manufacturer's rating of 19db.  (Please see the notes below on noiose reduction)
It is only 3/16" thick, so as not to interfere with proper mounting of your panels and seats, and all holes are pre-cut & all pieces are clearly labeled for your convenience.
It is our #1 goal to provide you ease of install, while making a improvement in your overall enjoyment of your Corvette.
Each kit is hand cut to our specifications and clearly marked for locationand.

Each kit comes with the following pieces:
  • Driver & Passenger front floorboard pieces, with holes cut for seat bolts and pedals.
  • Driver & Passenger side tunnel pieces, cut around your e-brake.
  • Full center console pieces, with holes for the center console bolts.
  • Full Cargo area floor pieces.
  • Full Side rear wheel well pieces.
  • Full back wall and corner pieces.
  • Full Center Well pre-cut pieces.
  • LH and RH Bottom sections of storage cubby's
  • Extra pieces for odds and ends coverage that you may need.


Say goodbye to over-heated center consoles, and noisy front cabins. The VetteNuts Insulation Kit is the perfect addition to your C5, and is recommended for every Corvette owner as the #1 modification for their Corvette. While GM did an outstanding job with the C5 they fell short in the insulation department. We feel our kit is the perfect addition to helping with heat and noise. 
Your Corvette will be cooler in the summer, a lot less noisy, and you will regain use of your center console once again.

A lot of research and development has gone into this kit, and we are proud to say that our kit is made to our demanding specs, in house, and cut off of our own templates.

Some have emailed and asked, so here is a picture of the material, as well as some specs on the material itself:

Two Kits Pre Installed together for Maximum Sound Deadning

Here is another great Insulation package from VetteNuts. It is a peel and stick Ensolite IUO insulation material pre installed on top of our Foil Kit. When these two kits are combined together it will come as one kit. Road noise inside your Vette is drastically reduced. Depending on road conditions are tire selection we have seen a 10 to 14db drop in cabin noise. We also provide some scrap material for you to use anywhere you like!

The Ensolite was designed by NASA for the space program. This is a very high grade foam/adhesive combination that will handle high heat, is fire retardant just like regular IUO. It resembles a wet suit material. This kit will make a huge difference in heat and road noise while adding only 9lbs to your Vette for both kits.

Vettenuts has sold 1000's of these kits and there is lots of reviews on
